COTE- IN Application filed iiovemher it, 1920.

To aZZ whom it may concern Be it known that l, Jase-an T CULLIN, acitizen of the United States, and residing at Detroit, in the county ofWayne and State of Michigan, have invented a new and -l'mprovedCoil-Winder, of which the following is a specification.

This invention relates to means for winding wire coils, particularly forelectric motors and generators, and is of the same general type as thatshown in my prior application Serial Number 407,708, filed September 2,19.20, and its object is to provide meanstor simultaneously shearingfree the two ends of the just previously wound coil and securing the endof the supply wire to a part ottlthe winder for the winding of the next(301 I This invention consists in combination with a winder for coilscomprising two members, one having a rectangular hub with inclined edgesand the other member being adapted to fit against and be secured to thefirst to cause the strands at the ends of the coil to keep their properpositions, of a shaft on which the winder is mounted, a plate on theshaft adjacent the winder and having a plurality of fingers, and shearmembers mounted on the plate and adapted to co-act with the fingers toshear the ends of the coil.

llt further consists in so positioning the shear membe'rsand thefingersthat the shear member which cuts the coil from the supply wirealso bends the end of the supply wire around one of the fingers so thatthe wire may be drawn from the supply when the winder is rotated.

lit also consists in so positioning another shear member that when thecoil is com pleted this shear memberwill cut ed the bent over end of thewire.

lit also consists in the detailsofconstruc tion illustrated in theaccompanying drawings and particularly pointed out in the claims.

In the accompanying drawings, Figure 1 is an elevation of this improvedcoil winder. Fig. 2 is a similar plan with the shearing means at theends oi the cutting strokes. Fig. 3 is a section on the line 3-3 asFig. 1. Fig. t is an end view talren from the left in Fig. 1. Fig; 5 isa plan otthe winding head and shear. Fig. 6 is a section on the line G tot Specification bf Letters Patent.

Similar reference characters refer to like parts throughout the severalviews.

Any desired means may be employed to support the spindle 1 and to rotateit the desired number of times to cause it towind a coll, as explainedin my former applicatlon. The outer end 2 of this spindle is preferablyenlarged and on it is slidable a sleeve 3 having a groove 4 and aconical outer end 5. A lever 6 pivoted at 7 has a pair of arms 8provided with pins 9 that extend into the groove l and by means of whichthe sleeve may be moved back and forth along the shaft.

A collar 10 and plate 11 are mounted on the outer end of the spindle andfrom the main portion of the plate extend the three fingers 13, 1d: and15 which carry the pivot 16 on which the shear levers A and B aremounted. The fingers l4: and 15 are similar, being provided withinclined faces 17 leading to the shear edges 18 onthese fingers. Theupper end 21 of the upper arm 22 of the lever A has a notch 23 toreceive the supply wir 20 from which the coil is wound, and when thislever is swung from the position shown in Fig. 1 to that shown in Fig.2, shears this wire in cooperation with the edge 18 of the finger 14.The forwardly extending upper end 24 of the upper arm 25 of the shearlever B cooperates with the shearing edge 19 of the finger 15 to shearanother portion of the wire at the same time as the shear lever A isoperating. The rear or lower ends 26 and 27 of these levers areconnected by the block 28 and the bolt 29. The end of the arm 27 isrounded to engage the conical end 5 of the sleeve 3. An outward movementof this sleeve will swing the cuttingedge of these levers across theshear ed es of the fingers 14: and 15. v

' ounted on the outer end of the spindle is a winder plate 30 and acentral pin 31 onto which a follower plate 32 maybe locked by means of alatch 33 after being positioned by the dowel-pins 34. The pin 81 has agroove 35 to receive the latch. The follower plate has a rectangular hub3'? and oppositely extending radial ribs 38, the edges of the hub beingbeveled as shown in Figs. 1 and 2.

A finished coil-39 is shown on the winder in Fig. and a clipetl is shownholding the wraps together so that they will not uncoil when released.The lever 6 is then swung llll 29 is started rotating. ;The supply wire20 to the position shown in Fig. 2, which causes the upper end 2l of theshear member A to. sever the end 42 of finished coil, which endimmediately falls, and the upper end 24 of: the shear member B to severthe supply wire 20 at 43, which permits the end 41 to spring out asindicated in Fig. 4. It

, will be noticed in Fig. 4' that there isa space between theside of theend 24 of the lever B and' up'per end of the adjacent finger I 14.'Whenthis end of the lever'is swung forward, it bends theend 44 (Fig.5)] of thesupply wire into this space and around the finger 14.

The latch 33 is then swung (to the right in Fig. 4) to release the 'p1n31,"andthe follower plate andthe. finishedcoil there- 'on is lifted offthe in 31 to permit the finished coil to fall. efol'lower is immediatelyreplaced and locked. and the shaft 1 swings down (relatively)*along thefront ed e of the finger 13 and is carried by the inc ined edge 45thereof'to the space b'etweenthe plates'30 and "32"of the winder whereinthe wire'is wound thedesired'num ber of wraps, passing in front of thefin ers 14 and v15 while being thus wound. net

before the winder stops, the operator guides th'e'wire into the notchesin the ends of thefingers into the path of the shear member 24, asshown'in Fig. 4.

The shear members are returned by the coilspring 46 which extends aroundthe collar'lO and has its ends hooked around the parts. 26 and 27 of theshear members, being held in osition by the pin 47 The operatortherefore has only to swing the lever 6, remove the plate 32 andreplace. it, start the shaft rotating, and at the end of the winding'uidethe supply wire into the notches in the ends of the fingers 14 and15. v j

The details and roportions of the several parts of this win ing machinemay all be changed by those skilled in the art Without departing fromthe spirit of my invention as set forth in the following clalms.

I claimsl 1. In a winding machine for coils the combination of a shaftand two winder plates mounted on the end thereof, and formed withcentral contacting portions on which the coils may be wound, and ashearing device mounted on said shaft and rotatable with said plates andhaving a plurality of cutting members to sever the ends of the finishedcoils. j v
